So Tsutomu was born in Showa 2 (1927), a student of his father So Masamitsu, a member of the All Japan Swordsmith Association, recipient of the Commissioner for Cultural Affairs Award, the Kunzan Award, and others, and became Mukansa in 1990 (Heisei 2) (at age 63), residing in Sanno, Hakata-ku, Fukuoka-shi. Regarding his style, he initially followed the Kotetsu style aimed for by his father, but later challenged the Kiyomaro style, succeeding brilliantly and eventually earning the nickname "Kiyomaro no So." He also challenged the toranba of the Sukehiro style, and the high level of his achievement was recognized when he became a Mukansa swordsmith in 1990 (Heisei 2). *What is Mukansa? This is a certification by the Nihon Bijutsu Token Hozon Kyokai granted to those who have won any of the special prizes at the New Sword Exhibition hosted by the association eight times or more, or those who have won special prizes six times or more, including the Prince Takamatsu Prize twice or more. The association certifies this, and it is also required that the individual possesses excellent character and skill. Normally, "Holders of Important Intangible Cultural Properties" (Living National Treasures) are recommended from among these Mukansa swordsmiths.
